GREATER Western Sydney vice-captain Stephen Coniglio remains in doubt for Saturday's clash with Gold Coast because of concussion, but the club has received some overdue good news on the injury front.

Coniglio copped a knock to the head last Sunday, when he helped the Giants to an upset victory over Adelaide that ended a four-match losing streak.

The midfielder is being closely monitored, with the club upbeat he may yet pass concussion tests and be cleared to play.

There's likely to be at least one change to the side that recorded one of the Giants' most important wins ever, with fit-again forward Matt de Boer expected to return.

The prospect of defender Adam Kennedy, who has been with the club since its formation, playing his first game in over a year will also bring a smile to the face of teammates and coaches.

Kennedy has recovered from a knee reconstruction and is set to return via the NEAFL this weekend.

"We're rapt to say that Adam will be available to play his first game," GWS fitness coach David Joyce said.

"We couldn't be more proud of the way he's gone about his rehabilitation."

Kennedy ruptured his anterior cruciate ligament (ACL) in round seven of the 2017 season, with co-captain Phil Davis choking up at the time as he answered questions about the foundation Giant's knee injury.

De Boer missed the past three games with a hamstring injury, having enjoyed a bright start to the season.

"He's at full strength and full confidence. He had a big session on the weekend and I expect him to be available," Joyce said.

GWS remains mired in an injury crisis, with Brett Deledio (calf), Toby Greene (foot), Tom Scully (ankle) and Zac Williams (Achilles) all unavailable.

Greene is likely to be the first of the four to return after the bye, although the All Australian small forward's comeback date remains unclear as he continues to recover from a persistent foot injury.
